AWWA EDC52033

Historically, water quality modeling has been limited to large skeletonized waterdistribution systems due to cost, data requirements and modeling softwarelimitations. This is no longer the case as illustrated in the case studydiscussed here. Freese and Nichols, Inc. conducted hydraulic and water qualitymodeling for the City of Brownwood, Texas (population 20,000) to determineappropriate system improvements. Older developed parts of the City's waterdistribution system had experienced poor water quality from water line corrosionresulting in a loss in chlorine residual. The purpose of the study was topinpoint these problem areas and devise a capital improvement program to improvewater quality throughout the water distribution system. This paper describes thesteps and constraints involved in conducting water quality modeling for a smallcity. These steps included field testing, model calibration, hydraulic and waterquality modeling, capital improvement plan development, and verification andoperation testing. Includes 3 references, figures.
